Nō nā tata nei, i whakaurua mai e Navitas te pūtake hiko o te pokapū raraunga CRPS 185 4.5kW AI, e whakamahi ana iYMIN's CW3 1200uF, 450Vngā pūnga hiko. Mā tēnei kōwhiringa pūnga hiko ka taea e te pūnga hiko te whakatutuki i te tauwehenga mana 97% i te haurua-kawenga. Ehara i te mea ka arotau noa tēnei whanaketanga hangarau i te mahi a te pūnga hiko engari ka whakapai ake hoki i te whai huatanga o te pūngao, inā koa i ngā kawenga iti. He mea nui tēnei whanaketanga mō te whakahaere hiko o te pokapū raraunga me te penapena pūngao, nā te mea ka whakaitihia e te mahi whai hua te whakapaunga pūngao engari ka whakaitihia hoki ngā utu whakahaere.
I roto i ngā pūnaha hiko o ēnei rā, kāore ngā pūnga hiko anake e whakamahia mōrokiroki pūngaome te tātari engari he mahi nui anō hoki tā rātou ki te whakapai ake i te tauwehenga mana. He tohu nui te tauwehenga mana mō te pai o te pūnaha hiko, ā, he pānga nui ngā pūnga, hei taputapu whai hua mō te whakapai ake i te tauwehenga mana, ki te whakarei ake i te mahi whānui o ngā pūnaha hiko. Ka tūhuratia e tēnei tuhinga te pānga o ngā pūnga ki te tauwehenga mana, me te matapaki i tā rātou mahi i roto i ngā tono mahi.
1. Ngā Mātāpono Taketake o ngā Pūnga
He wāhanga hiko te pūnga hiko e rua ngā ara iahiko (ngā irahiko) me tētahi rauemi ārai (te hiko-kore). Ko tana mahi matua he penapena me te tuku i te pūngao hiko i roto i tētahi ara iahiko aukume (AC). Ina rere te iahiko AC i roto i tētahi pūngao, ka puta he mara hiko i roto i te pūngao, hei penapena pūngao. I te huringa o te iahiko, kapūngahikoka tukuna tēnei pūngao kua rongoatia. Mā tēnei āheinga ki te penapena me te tuku pūngao ka whai hua ngā pūngao ki te whakarerekē i te whanaungatanga ā-wāhanga i waenga i te iahiko me te ngaohiko, he mea tino nui tēnei ki te whakahaere i ngā tohu AC.
E kitea ana tēnei āhuatanga o ngā pūnga hiko i roto i ngā mahi whaihua. Hei tauira, i roto i ngā ara iahiko tātari, ka taea e ngā pūnga hiko te aukati i te iahiko tika (DC) me te tuku i ngā tohu AC kia puta, ā, ka whakaitihia te haruru i roto i te tohu. I roto i ngā pūnaha hiko, ka taea e ngā pūnga hiko te whakataurite i ngā piki me ngā heke o te ngaohiko i roto i te ara iahiko, ka whakarei ake i te pumau me te pono o te pūnaha hiko.
2. Te Ariā o te Tauwehe Mana
I roto i te ara iahiko AC, ko te tauwehenga mana ko te ōwehenga o te mana tūturu (mana tūturu) ki te mana kitea. Ko te mana tūturu ko te mana kua hurihia hei mahi whai hua i roto i te ara iahiko, ko te mana kitea ko te mana katoa i roto i te ara iahiko, tae atu ki te mana tūturu me te mana tauhohe. Ko te tauwehenga mana (PF) ka hoatuhia e:
ko P te mana tūturu, ā, ko S te mana kitea. Kei waenga i te 0 ki te 1 te tauwehe mana, ā, ko ngā uara e tata ana ki te 1 e tohu ana i te pai ake o te whakamahinga mana. Ko te tikanga o te tauwehe mana teitei ko te nuinga o te mana ka hurihia hei mahi whai hua, engari ko te tauwehe mana iti e tohu ana he nui te mana e maumauria ana hei mana tauhohe.
3. Mana Tauhohe me te Tauwehe Mana
I roto i ngā ara iahiko AC, ko te mana tauhohe e pā ana ki te mana i puta mai i te rerekētanga ā-wāhanga i waenga i te iahiko me te ngaohiko. Kāore tēnei mana e huri hei mahi tūturu engari kei te noho tonu nā ngā pānga rokiroki pūngao o ngā inductors me ngā capacitors. Ko ngā inductors te tikanga ka whakauru i te mana tauhohe pai, ko ngā capacitors ia ka whakauru i te mana tauhohe kino. Ko te noho mai o te mana tauhohe ka hua ake te hekenga o te pai o te pūnaha hiko, nā te mea ka whakanui ake i te kawenga katoa me te kore e whai wāhi ki te mahi whai hua.
Ko te hekenga o te tauwehenga mana e tohu ana i te pikinga ake o te taumata mana tauhohe i roto i te ara iahiko, ka heke te whai huatanga whānui o te pūnaha mana. Ko tētahi huarahi whai hua ki te whakaiti i te mana tauhohe ko te tāpiri i ngā pūnga, ka taea te āwhina ki te whakapai ake i te tauwehenga mana, ā, hei whakarei ake i te whai huatanga whānui o te pūnaha mana.
4. Te Pānga o ngā Pūnga ki te Tauwehe Mana
Ka taea e ngā pūnga hiko te whakapai ake i te tauwehenga mana mā te whakaiti i te mana tauhohe. Ina whakamahia ngā pūnga hiko i roto i te ara iahiko, ka taea e rātou te whakakore i ētahi o te mana tauhohe e whakaurua mai ana e ngā inductors, ā, ka whakaitihia te mana tauhohe katoa i roto i te ara iahiko. Ka taea e tēnei pānga te whakanui ake i te tauwehenga mana, ka tata atu ki te 1, ko te tikanga ka tino pai ake te whai huatanga o te whakamahinga mana.
Hei tauira, i roto i ngā pūnaha hiko ahumahi, ka taea te whakamahi i ngā pūnga hei utu mō te mana tauhohe e tukuna ana e ngā kawenga whakauru pēnei i ngā motuka me ngā whakawhiti hiko. Mā te tāpiri i ngā pūnga tika ki te pūnaha, ka taea te whakapai ake i te tauwehenga mana, ka whakaiti i ngā ngaronga mana me te whakapiki i te whai huatanga o te whakamahinga pūngao.
5. Te Whirihoranga Pūnga i roto i ngā Whakamahinga Whaihua
I roto i ngā mahi whaihua, he maha ngā wā e pā tata ana te whirihoranga o ngā pūnga hiko ki te āhua o te kawenga. Mō ngā kawenga whakauru (pērā i ngā motuka me ngā whakawhiti hiko), ka taea te whakamahi i ngā pūnga hiko hei utu mō te mana tauhohe i whakaurua mai, ā, mā reira ka whakapai ake i te tauwehenga mana. Hei tauira, i roto i ngā pūnaha mana ahumahi, mā te whakamahi i ngā pēke pūnga hiko ka taea te whakaiti i te kawenga mana tauhohe ki runga i ngā whakawhiti hiko me ngā taura, ka whakapai ake i te pai o te tuku mana me te whakaiti i ngā ngaronga mana.
I roto i ngā taiao kawenga nui pēnei i ngā pokapū raraunga, he mea tino nui te whirihoranga o te pūnga hiko. Hei tauira, ko te pūtake hiko pokapū raraunga Navitas CRPS 185 4.5kW AI e whakamahi ana i ngā YMIN.CW31200uF, 450Vngā pūnga hiko hei whakatutuki i te tauwehenga mana 97% i te haurua-kawenga. Ehara i te mea ka whakarei ake tēnei whirihoranga i te whai huatanga o te tuku hiko engari ka arotau hoki i te whakahaere pūngao whānui o te pokapū raraunga. Mā ēnei whakapainga hangarau ka āwhina i ngā pokapū raraunga ki te whakaiti i ngā utu pūngao me te whakarei ake i te pumau o te mahi.
6. Mana Utaina-Haurua me ngā Pūnga
Ko te mana haurua-kawenga e pā ana ki te 50% o te mana kua whakatauria. I roto i ngā mahi whaihua, mā te whirihoranga tika o te pūnga ka taea te whakapai ake i te tauwehenga mana o te kawenga, ā, mā reira ka whakapai ake i te whai huatanga o te whakamahinga mana i te haurua-kawenga. Hei tauira, ko te motuka me te mana kua whakatauria o te 1000W, ki te mea he pūnga tika, ka taea te pupuri i te tauwehenga mana teitei ahakoa te kawenga o te 500W, kia pai ai te whakamahinga pūngao. He mea nui rawa atu tēnei mō ngā mahi me ngā kawenga hurihuri, nā te mea ka whakarei ake i te pumau o te mahi a te pūnaha.
Whakamutunga
Ko te whakamahinga o ngā pūnga hiko i roto i ngā pūnaha hiko ehara i te mea mō te rokiroki me te tātari pūngao anake, engari mō te whakapai ake i te tauwehenga mana me te whakanui ake i te whai huatanga whānui o te pūnaha hiko. Mā te whirihora tika i ngā pūnga hiko, ka taea te whakaiti nui i te mana tauhohe, ka taea te arotau i te tauwehenga mana, ā, ka taea te whakanui ake i te whai huatanga me te whai huatanga utu o te pūnaha hiko. Ko te mārama ki te tūranga o ngā pūnga hiko me te whirihora i a rātou i runga i ngā āhuatanga kawenga tūturu te mea nui ki te whakapai ake i te mahi a ngā pūnaha hiko. Ko te angitu o te pūhiko pokapū raraunga Navitas CRPS 185 4.5kW AI e whakaatu ana i te kaha nui me ngā painga o te hangarau pūnga hiko matatau i roto i ngā tono mahi, e whakarato ana i ngā māramatanga whai hua mō te arotau i ngā pūnaha hiko.
